Probably you are inside a corporate firewall that introduces certificates into the network traffic that are not rooted on a certificate in the JRE running the IDE.

Adding the two settings described here to the end of your eclipse.ini might fix the problem (though no one ever seems to come back to let us know whether or not that helps):

it seems to have solved that problem but once I try the installation it gives me the following error:

"Artifact not found: http://downloads.genuitec.com/downloads/products/codetogether/updates/ct20230322/features/com.genuitec.eclipse.codetogether.client.feature_2023.1.0.202303212042.jar."

Sometimes firewalls do a number of additional funky things, including scanning jars and taking so long to do so that it looks like a network timeout. Maybe repeated tries will eventually be able to download it...

As someone who has to deal with a corporate firewall, if I had gotten the error you describe, I would assume that the JVM running Eclipse didn't have the correct company-specific certificate installed in the cacerts file. If that was not the case, or you know nothing about this, the next thing to try is to try to turn off the VPN you use to connect to your corporate network (and turning off any proxy entries you have in Network Connections), and then try to install the plugin. Once it's all installed, you can reconnect to the network.
